The Catholic Church teaches that the highest type of worship (latria) is to be given to the Blessed Sacrament. This doctrine follows logically from two revealed truths: that Jesus Christ, even in His humanity, on account of His Divine personality is worthy of Divine homage; and that Jesus Christ is really present in the Blessed Sacrament. Most illogical therefore is the attitude of those who admit the doctrine of the Real Presence, but refuse to give external adoration to the Eucharist. The manner of showing homage to the Blessed Sacrament has varied in the Catholic Church in different ages. In the Oriental rites a profound bow is the usual act of adoration. In the Latin Church a genuflection is made, single if the Blessed Sacrament is in the tabernacle, double if it is exposed.
